Jasher
    upright. "The Book of Jasher," rendered in the LXX. "the Book of
    the Upright One," by the Vulgate "the Book of Just Ones," was
    probably a kind of national sacred song-book, a collection of
    songs in praise of the heroes of Israel, a "book of golden
    deeds," a national anthology. We have only two specimens from
    the book, (1) the words of Joshua which he spake to the Lord at
    the crisis of the battle of Beth-horon (Josh. 10:12, 13); and
    (2) "the Song of the Bow," that beautiful and touching mournful
    elegy which David composed on the occasion of the death of Saul
    and Jonathan (2 Sam. 1:18-27).



 Jasher, righteous; upright
